HOTEL-LOCK.

To all whom it mayconcern: 1

Be it known thatI, JoI'IN'HiSrlAngac tie zen of the United States,vresiding at New Haven, in the county of New Haven: and State ofConnecticut, have invented a new and useful Improvement in I'IoteLLocksyand I do hereby declarethe following, when. I taken inc'onnectionwiththe accompanying drawings and the characters offrefrrencemarked thereon, to be affull, clear, and.

exact description of the same, and which said drawings constitute partof this specie fication, and represent, in y Figure la broken. view ofthe lock insidev .elevationwith the cover removed bothboltsr;

in their retracted positions and the emer gency-gate in its clearanceposition. Fig. 2 a corresponding view showingthe inside, bolt in itslocked position and the emergency-gatein its blocking position, Fig. 3

Fig. 5 a detached plan view of theemergency-gate. guests key. .Fig. 7 a plan view of the maids or masterkey. of the proprietors or emergency key- My inventionrelates to animprovement in that class ofhotel locks which are furnished with aguests key,a series of maids or master keys, and a proprietors oremergency key, the object being to produce a simple, convenientandreliable lock of the character described, constructed with particularreference to being readily converted. from a right-hand door lock. to aleft-hand door lock, and vice versa.,- v

It is also aimed to provide. an improved construction and arrangementofv movable ward or emergency gate particularlyadapted for use in locksof the general type illus trated in Letters Patent No. 898,434,.grantedto Sargent & Company, on September 15, lQOS, as assignee of William J.Carroll, but likewise adapted to looks of other types. 7

More particularly, the inventioncontemplates the provision of areversible ward ,or emergency gate independent of the bolt to Fig. aplan view of the Fi 8 a Jlan view Specification of L'ettrsPatent. t t A17, 1 15 I Application filed. April'lO, 1911. Serial No. 620,016; I

which it relates, and the improved construct ion,fmounting orarrangement and operationof suchward or gate.

To these and other ends, the invention consists in the novel featuresand combina-- tlons of parts tobe hereinafter described versibleedge foredge for the conversion of I the look from a right-handdoor lock to aleft-hand door. lockjand vice versa. This gate which, as shown, slidesupon the lower wall 3 of the lock-case 4 within said locklongitudinalmovement of the gate, is moved so as to obstruct the fulland proper entrance into the outside keyway Got the lock for all keysexcept the proprietors or. emer gency key 7 the said keyway 6 beingformed in thelock-case and. partly. in the cover 8 thereof, n I

As herein shown the said gate 2 isformed near itsouter end and in itsopposite edges with two notches 9 one or the other of which receives,according to the position of the gate,t-he lower end ofanoperating-lever 1O resting: uponthe back of theloclocase 4L, turningupon a-stud 11 and having its upper end entered into a notch '12 inthelower edge of theupper bolt 13 which is operated only from theinsideof the door furnished with the lock and for that reason commonly Iknown in the art as an inside bolt.

The lock illustrated is of the general type shown, in the abovementionedCarroll patent. r

The said inside bolt 13 is provided as usual with a single pivotallever-tumbler 14: having a gate 15 lGCGlVHlg a post '16 mounted in theinner end of the belt at a point ,case is provided upononeedge atits-inner end with a blocking-finger 5 which,.in the above the talons 17and 18 thereof. The

link 21 with the inner ends of a gang of lever-tumblers 22 mounted uponthe outside bolt 23 which is located below the inside bolt maids ormaster-keys 28 none of which. can

be operatively introduced into the outside keyway 6 when the'inner bolt13 is in-its locked position, since at that time the emergency-gate 2occupies its blocking position in which its, finger 5 obstructs theoutside keyway 6 suflioiently to prevent the fullor proper introductioninto it of an key except the special proprietors or emergency key 7designed with particular reference to this lock. I v V I may now saythat my present invention does not concern itself with the particularconstruction of the inside bolt 13 or of the outside bolt 23, or of anyof the parts connected therewith as long as they permit the employmentof my improved emergencygate 2'and its connection with the inside bolt13 soas to beoperated thereby to obstruct the outside keyway 6 when thesaid inside bolt is in its locked position.

To convert my improved look from a right-hand door lock to a left-hand 1door lock, or vice versa,it is necessary only to remove the lock-cover 8and reverse thegate 2 edge for edge and also to turn the latchbolt 29over face for face in the usual man ner. I

. In one adjustment, the plate-like ward or gate is adapted to extendinto one end of the keyway or keyhole, and in the other adjustment, i.6., when said ward is turned edge for edge, it is adapted to extend intothe keyhole or keyway at the opposite end. \Vhen the ward is in blockingposition, it not only prevents the operation of the bolt by a certainkey or keys, but it even prevents a full insertion or introduction ofsuch key or keys into the lock, and yet the reversibility of the ward orgate permits the look to be adjusted to the desired functions of theseveral keys at the respective sides of the look.

In the use of my improved lock, the guest unlocks the room door byinserting the guests key 19 into the outside keyway 6 of the look. Whenonce inside the room, he looks the door by inserting the same key 19into the inside keyway 20. Now by turning the key he throws the insidebolt 13 into its locked position. As the said bolt moves into its lockedposition, it swings the lever 10 whichin turn positively slides theemergency-gate 2 into its obstructing position in which its finger 5stands across the outside keyway 6 and prevents any key from being fullyand properly introduced into the look from the outside of the doorexcept the emergency-key 7 which is constructed with particularreference to clearing the blocking-finger 5 of the key. In other words,the blocking-finger 5 of the gate 2 prevents the proper introductioninto the look from the outside, of any of the series of maids ormaster-keys designed for use with the look so that the occupant of theroom is secure against intrusion from any one holding any of the maidsor master keys so long as the lock is locked from the inside by thethrowing of the inside bolt 13.

What I particularly wish to call attention to is the fact that under'myinvention it'is not necessary to initially construct the locks for useon right hand doors or on left hand doors since all of the locks may beconverted by any purchaser for one use or the other by simply removingthe lock-cover S and reversing the gate 2 edge for edge and reversingthe latch-bolt 29 face to face.

Of course I have not attempted to illustrate and describe the numerousmodifications of the construction which may be adopted within the scopeof the appended claims. In certain aspects of the invention, the kind oflook, i. 6., whether provided with one bolt, or with a plurality ofbolts, V

is immaterial. In some aspects of the invention, the particular mountingof the movable ward or gate is the essential feature, and in stillothers, the reversibility of a ward or gate of the general type hereindescribed.
